Things to check first
No sound?
Check the device and game volume, silent mode and connected headphones.
Connection or records not loading?
Check your internet connection and reopen the game. Do not clear app data or browser storage before checking whether your records have been saved.
A purchased item is missing?
Check that you are using the same store and account used for the purchase. Contact us before paying for the same item again.
If the problem continues, email us. Not every platform provides the same features or products.
Privacy and account deletion
Use the privacy notice, account-deletion guide and terms below to check the rules for your platform. Uninstalling the app or signing out does not delete the server account or game records. Account deletion and cancellation of a store subscription are separate procedures.
iPhone and iPad
As checked on 3 October 2026, version 1.0 is available in the Korean App Store. Public build 39 has no ads. The 1.0.1 update with optional rewarded ads is under review.
“Play without signing in” creates an anonymous guest account without registering a name or email. When the server is available, records, purchase entitlements and mailbox items are linked to that account. Google or Apple sign-in is optional. If the account server is unavailable, device-only play is possible, but purchases are unavailable in that mode.
The payment server is connected, and Sandbox test purchases and grants have been checked. Real commercial transactions and purchase/restore checks for a newly created guest account on a physical device have not yet been fully verified. Public build 39 does not initialize the ad SDK, request ads or UMP consent, or use ATT/IDFA tracking. See the iOS section of the privacy notice for the 1.0.1 rules.
Guest accounts can also request deletion through My Account → Delete BEATWAVE Account. These are translated descriptions of the existing menu; displayed wording depends on the app version. The operating standard is manual processing within seven days after the in-app request is received. Receiving a request is not the same as completing deletion.
